Embodiment Construction

[0025] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0026] Such as Figure 1-3 Shown, the construction method of the column of the belt conveyor of a kind of high landfill area, comprises the following steps:

[0027] Step 1: Dig the foundation pit according to the construction drawing; the length, width and depth of the foundation pit are 2500mm, 2500mm, and 1300mm;

[0028] Step 2: compacting the pit bottom of the foundation pit to form a compacted plain soil layer 1, and then detecting the compaction coefficient of the compacted plain soil layer;

[0029] Step 3: Drive the steel pile after derusting and painting into the rammed plain soil layer at the bottom of the foundation pit for 1 mile;

[0030] Step 4: Pouri...

Abstract

The invention discloses a construction method for stand columns of a belt conveyor in a high landfill area. The construction method comprises the following steps: (1) a foundation pit is excavated according to a production drawing; (2) the bottom of the foundation pit is compacted; (3) derusted and painted steel piles are driven into a compacted soil layer at the bottom of the foundation pit; (4) a concrete cushion layer is cast according to the production drawing requirements; (5) base plate reinforcements are paved according to the production drawing; and column reinforcement cages are paved according to the production drawing; (6) independent foundations are cast; (7) the stand columns are cast; and (8) soil is filled in the foundation pit, and is compacted. The construction method can improve the foundation bearing capacity to enable the stand columns to meet the operation requirements of the belt conveyor, is simple in construction operation, short in construction period, high in practicability, lower in construction noise, free of pollution, and is an economical foundation treatment mode with environmental protection and energy conservation.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a construction method for a column of a belt conveyor in a high landfill area. Background technique [0002] The trestle of the belt conveyor is a frame structure, on which there is a belt conveyor for transferring coal, which is sensitive to settlement, and the characteristic value of the foundation bearing capacity of the independent foundation under the column is required to be not less than 0.2MPa; The foundations are all miscellaneous fill and construction waste, and the bearing capacity of the foundation is very low, which cannot meet the design requirements. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a construction method for the column of the belt conveyor in the high landfill area, improve the bearing capacity of the foundation, so that the column can meet the operating requirements of the bel...
